Javier Arribas b849b20a8c Added optional support for Sparkfun SiGe GN3S USB GPS RF sampler:
- Added a pre-compiled custom GN3S firmware.
- Added a fully-compliant GNU Radio source block for GN3S USB dongle. It can be used also from GNU Radio companion and from Python applications.
- Added a new GN3S_Signal_Source block. It is possible to disable the GN3S signal source compilation. See README.
